SPEGEICATION forming part of Letters Patent No. 398,778, dated February 26, 1889.

Application filed May 4, 1888, Serial No. 272,837. (No model.)

To all wiwi/t muy cfr/werte:

15e it known that I, WINFIELD O. (insonne,

3 the ilangc ol" the valve-casing, and also serve a citizen ol the United States, residing at` Terre llaute, in the coun ty oi Vigo and State p ot' Indiana, have invented certain new and use i ful Improvements iu Hteain-liloiler Feeders; and I do hereby declare the ibllowin to be a full, clear, and exact ijlescription of the invention, such as will enable others skilled in the art to which i1 appertains to make and use the p ,l the valve-rod e is passed through the float.v

same.

This invention relates to regulator-s which are adapted to keep the water in a steamboiler at a substantiall;v uniform level, and is an improvement in the device for which I filed an application for Letters Patent on March 2, i888, Serial No. 265,901.

The present invention consists in the novel construction and combination oi' the parts, i

hereinafter fullyv described and claimed, whereby the regulating-valve may be operated by hand to change the water-level ofthe boiler, and whereby the weight of the regulating-valve and the float may be counterbalanced.

In the drawings, Figure l is a vertical seetion through the device. Fig. L is a plan view of the device.

A is the e'vlinfllrical balanced regulatingvalve provided with holes d. B is the cylinder in which the valve works, provided with annular orifice@ h, and o is t-he tl ange b y which the said c vlinder is held in position. C is the casing,` for the valve and its cylinder, provided with a iiange, c, at the top, and D is the inlet for the water from the pump. All these parts are the same described in my aforesaid application, and the inlet-pipe provided with a safetyvalve in a similar manner, but not shown in the drawings forming a part of this application.

' E is the iioat, and (f is the regulaiingwalve rod; but according to this invention the float is not secured to the said rod direct, but is fastened upon. the end ot' a lever, E', pivoted on t-he pin F, which passes through the double eyef at the lower end of the vertical spindle F', the upper end of which is provided with a screw-threaded portion j".

G is the casing for the iloat and its lever. l

This casing is provided with the flange g at l its base, and g are bolts which secure it to l the boiler is reduced and the regulating-valve to secure the vz'ilvc-cylindertlange in position between the two said flanges.

l the outlet t'or the water which goes into the boiler after passing through the regu lating-valve. The valve-rod e is provided with a yoke, Il, through which thelever E passes, and h is an enlargement upon the said lever which tits the slot inthe `volte and enables the lioat to operate the valve. The upper end of casing, and l is a stul'tng-box Afor keeping it casing.

.l is an adjustable weight upon the end of lever i' for counterbalancing the weight of all the moving parts inside the easings, which are connected with the regniating-valve rod when the ioat is at the water-level.

l is a cover for the loat-casing above the float, and is a steampipe by which the upper part of the easing is placed in communication with the steam-space ol the boiler, so that the pre ssure in both mav always be the same.

The spindle F is passed through the Iioat' casing, and L is a sluiting-box for preventing the escape of steam.

)I is a hand-wheel provided with a screwthreaded sleeve, m, which engages with the screw-threaded end oi" the spindle.

N is a standard secured to the casing, and n is a journal formed on the outside of the sleeve, so that it may revolve in the hole at i the top of the standard without moving vertically.

IOO

requires to be opened, so that niore water may enter the boiler.

l. The combination, with the regulatingvalve of a steam-boiler feeder, of a lever and a float for operating the valve, and handactuated screw for altering the position of the fulcruni of the said lever, thereby permitting the water-level of the boiler to be changed, substantially as and for the purpose set forth.

2. The combination, with the regulatingvalve of a steam-boiler feeder, of a lever and a float for operating the valve, an adjustable fulcruin-for said float-lever, and a weight for eounterbalanein g the said valve and float when the AIioat is supported at any desired water-level, substantially as and for the purpose set forth.

3. The combination, with the regulatingvalve of a steam-boiler feeder, of a lever and a oat for operating the valve, andan adjustable fuleruin for the said float-lever, substantially as 'and for the purpose set forth.

4. The combination, with the regulating valve of a steamboiler feeder, of the valvestein connected to the valve, the float, the iioat-lever operatively connected to the said valve-stein, the vertical screwed spindle provided with a fulcrum-pin for the float-lever, and a revoluble screw-threaded sleeve for adjusting the position of the vertical spindle, substantially as and for the purpose set forth.

5. The combination, with the regulatingvalve of a steam-boiler feeder, of the valvesteni connected to the valve and provided with a yoke, the float, the float-lever provided with an enlargement engaging with said yoke, the screwed spindle projecting through the iioatcasing and provided with a fuleruin-pii'i for the lever at its lower end, a standard secured outside the float-casing, and a revoluble screw- .threaded sleeve journaled in the standard for operating the said spindle, substantially as and for the'purpose set forth.

G. The combination, with the Vregulatii'igvalve of a steam-boiler feeder, of the valvestein connected to the valve, the iloat, the

iioat-lever operatively connect-ed to the said valve-stem, the vertical screwed spindle provided witli a fulcruin-pin for the float-lever, a revoluble screw-threaded sleeve for adjust`- ing the position of the vertical spindle, a lever pivoted to the end of the valve-stem, a stand pivotally supporting the said lever, and a weight upon the free end of the said lever for counterbalancing the regulating-valve and other moving parts when the float is supported at the water-level, substantially as and for the purpose set forth.

In testimony whereof I affix iny signature in presence of two witnesses.
